Marc Cain sheer joggers

Beautiful joggers with elastic waistband and ankle cuffs. the fabric is shiny blue/black that looks navy in the light. very light and airy, bought in the wrong size. oh how I wish these fit me. I don't know the actual size but I'm a size 10 and they go on, but have 0 flex in the legs. So as much as the waist measures at 15.5 inches, these do not fit like a 10. I'd say a size 4-6? they have a sheer layer and thin black lining. they're beautiful.
